General Description
Functional Diagram
The HMC434 is a low noise Divide-by-8 Static
Divider utilizing InGaP GaAs HBT technology
in an ultra small surface mount SOT26 plastic
package. This device operates from DC (with a
square wave input) to 8.0 GHz input frequency
with a single +3.0V DC supply. Single-ended
inputs and outputs reduce component count and
cost. The low additive SSB phase noise of -150
dBc/Hz at 100 kHz offset helps the user maintain
good system noise performance.

Note: Line lengths on pins 1 & 4
(N/C) are not necessary.
List of Materials
The circuit board used in the final application should
use RF circuit design techniques. Signal lines should
have 50 ohm impedance while the package ground
leads should be connected directly to the ground
plane similar to that shown. A sufficient number of via
holes should be used to connect the top and bottom
ground planes. The evaluation circuit board shown is
available from Hittite upon request.
